METAL CONTAINER.

Specification of Letters Patent.

Patented Nov. 29, 11921.

Application filed September 23, 1920. Serial No. 412,273.

To all whom it may concern:

Be it known that I, HUGO P. GEIsLER, a citizen of the United States,residing at 720 Riverside Drive, New York, N. Y., have invented certainnew and useful Improvements in Metal Containers, of which the followingis a specification.

My invention relates to containers with a metal end or ends whosecontents are liable to evolve gas, thus causing the walls to swell orthe ends to bulge, and which are often rejected erroneously because of abulging of the tops not due to fermentation but to the shocks or blowsgiven by the contents to the ends or sides, in their transportation, orin the handling of the containers.

Oneof the objects of my invention is to greatly lessen or prevent thebulging and buckling of the ends,.and also to prevent what are known inthe trade as springers. or slackers produced by the dropping of thecontainer or case in which the containers are packed for shipment.

Another object of my invention is to enlarge the carrying capacity ofthe container without enlarging its size where the material within thecontainer is such that will not permit the soldering of the ends to thebody of the container.

Another feature of my invention is, to construct a rim or flange on acontainer that will act as a base or cushion against which the ends restand press in the event of pressure from within; also to prevent thesides of the container being torn away from the ends of the flange orrim joint of the container, in the event of the container becomingcrushed.

Another object is to construct a rim or flange on a container that willbe air tight and leak proof without the aid of a gasket.

One or more illustrative embodiments of my invention are represented inthe accompanying drawing, viz.

Figure 1 is a side elevation of a container embodying my invention, thetop and bottom being the same.

Fig. 2 1s a top or bottom view of the container of Fig. 1.

Fig. 3 illustrates one step in making the flange.

F1 s. 4 and 5 are sectional views showing two onus of flange or rim ofthe container and the manner in which the ends (top and bottom) arefastened to the side or body of the container and held in place.

' j ected, thus 'causlng Fig. 6 shows a top with a different kind ofcorrugation.

Fig. 7 is a section of the lower portion of the contalner shown in Fig.6, on line 1-1.

Shipments of metal containers such as cans of condensed milk arefrequently regreat loss, because of the appearance of swelled, bulged orbuckled ends on some of the cans, erroneously attributed to spoiledcontents due to fer- 'mentation and gas forming inside the containerwhereas in many cases the buckled or bulged ends arise from the blowgivento the ends of the containers by their contents when they aredropped from a height or violently knockedin shipping. Although thecontainers are stacked upon each other their ends are unsupported andare free to move under the blows and shocks dealt by their metal betweenthe corrugations will not'be' flexed, due to shocks on the ends orcrushing of the sides. The entire center of the ends (top and bottom) isridged and non-flexible when crushed or dented at the sides of thecontainer. The spaces between the ribs are preferably not wider than theribs. due to spoiled contents and consequent gas formation withresulting high pressure will, however, bulge the sides of the containeror even the tops so that they can be readily detected and the cansrejected.

Referring to the drawings, it will be observed that in the constructionof the ends from tin or other metal, I, by suitable means, formpreferably in ridges straight across as shown in Fig. l, at 1, all or aportion of the metal'forming the ends (top and bottom) surrounded by theflange or rim 2 of the container. I leave a slight space 3 which may beused for cutting purposes between the ends of the corrugations 1 and theflange or rim 2 in such a manner as to give the greatest strength andrigidity to the metal used and serving to anchor the ends of thecorrugations therein.

The corrugations 1 in the ends (top and swells I bottom) of thecontainer are to be of suflicient height and of suflicient number so asto give the requisite strengthand rigidity to the metal used, accordingto the size of the container, and are preferably of uniform width anduniformly spaced. The corrugations are so closely spaced that the metal"between the corrugations will not be flexed, due to shocks on the endsor crushing of the sides. They are of such a height that the outsidesurface of the ends (top and bottom) 1*, 1 1 will, when the endsare inplace on the container, be approximately on a level with the top of theedge of the rim or flange 2 or side. of the container. Or the ends (topand bottom) of the container, may be crimped in any design desired andthe ends (top and bottom) slightly bulged outward, sothat the outsidesurface and center of the ends (top and bottom) will, when the ends areattached to the body of the container, be on a level with the top of theedge of the rim or flange 2 or side of the container (see Fig. 7).

11 either case the outside surface 1, 1 1 of the ends (or center whenbulged outward) as well as the rim or flange 2 of the container will beapproximately flush with, or resting approximately on the shelf orarticle on which the container is placed. Or, in shipin when onecontainer is placed on top oft e other, (end to end) the outside surface1*, 1, 1 of the ends, as well as the flange or rim 2 will be restingagainst each other,

thereby preventing the ends (top and bottom) from bulging, springing orbuckling in the event of rough handlin or being dropped while packed incases for s ipment.

Where the container is constructed as a receptacle for articles thatwill not permit the soldering of the ends to the container afterfilling, as when used to store condensed ceptacle for oils, gelatin likecompounds milk, the outside portion 4, 4* of the metal of the ends issuitably bent so as to form a groove (Fig.3) with sides of equal depthto fit and slip over the top 5 of the side 5 (Fig. 3) of the container,Before putting the ends on to the container and fastening them in place,the groove in the end into which the top 5 of the side 5 of the.container is inserted may, or may not, be filled with a proper selfcementing substance as for example, paraflin, waxy or resinous compoundsof a suitably high melting point; or, when the containers are to be usedasa reinsoluble in oil, may be used, the kind depending upon the articlethe container is to hold. After placing the ends on the container andinserting the top 5 of the side 5 into the groove (Fig. 3) the same istightly crimped and compressed, and then may be bent outward and crimpedas in Fig. 4, but preferably according to the best em- -bodiment of myinvention, bent inward and down against itself, and again tightlycrimped and. compressed forming the rim or flange 6 of Fig. 5 with top 6and base 6 The rim or flange so formed more securely fastens the ends tothe container, gives a long anti-leakage path, and acts as a base orcushion against which at 6 the ends (top and bottom) rest or press inthe event of pressure from within. The rim or flange so formedproduces'a more rigid and air tight flange, rim and joint, than presentmethods; and also prevents the side 5 from being torn away from theflange in the event that the container be crushed; besides reducing theeffective diameter of the container at the ends by the thickness of therim or flange,

if it were on the outside, thus enabling more containers to be packed inthe same space.

The flange is free from leakage and does away with the use or necessityof a gasket that is now used and in many cases found objectionable tothecontents of the tins or containers, where an air tight and leak proofjoint, flange or rim is required.

In the embodiment of the invention shown -in Figs. 6 and 7 thecorrugations 8 start a short distance from the rim, to give a cuttingstrip which anchor the ends of the corrugations, and run spirally towardthe central portion, leaving space for a number or mark. The centralportion or topmost portion 9 is on a level with the rim.

Where the container is constructed to act as a receptacle for articleswhere the ends (top and bottom) of the container, the outside portion ofthe tin, or metal of the ends surrounding the crimp or corrugation issufiiciently raised and formed so that when the ends are fastenedandsoldered to the container, the outside surface of the ends will likewisebe approximately on a-level with the top of the edge or side of thecontainer, the same as containers where the ends are not soldered, asheretofore described.
